“We found out on my birthday, which was pretty cool,” President Trump’s 33-year-old son told People magazine.

Lara Trump, who is also 33, told People that she experienced fatigue and exhaustion early on in her pregnancy, but is now feeling wonderful. She added that her father in law was “so excited” to find out.

“We were worried he’d blurt it out at a press conference,” she laughed.

On Monday, Trump retweeted his son’s post with the following message: “Congratulations Eric & Lara. Very proud and happy for the two of you!”
